RESUMO
Objective To investigate the reason of persisting positive rapid plasma reagin (RPR) in serofast syphilis patients, and to provide reference for clinical treatment and prognosis.Methods A total of 33 serofast patients and 23 healthy controls were enrolled in this study.The percentages and absolute counts of CD3+, CD4+, CD8+ T lymphocytes and natural killer (NK) cells were detected by flow cytometry.The comparison of two groups was analyzed by independent sample t test, and the correlation between change of lymphocyte subgroups and RPR titer in serofast syphilis patients was analyzed by bivariate linear correlation method.Results Compared with healthy controls, the percentages of CD3+, CD8+ T lymphocytes in serofast syphilis group were both increased significantly (75.75±5.76)% vs (68.37±5.80)%, (t=4.69, P<0.01);(27.34±7.02)% vs (24.33±1.95)%, (t=2.34, P=0.025), while both the percentage and absolute count of NK cells were significantly decreased (7.32±4.48)% vs (14.87±6.26)%, (t=5.269, P<0.01);(136.2±83.4)/μL vs (298.8±166.9)/μL, (t=4.311, P<0.01).RPR titer of the patients was negatively correlated with both percentage and absolute count of CD4+ T lymphocytes (r=-0.476 and-0.515, respectively, both P<0.01), and it was positively correlated of CD8+ lymphocytes (r=0.588 and 0.305, P<0.01 and P=0.804).Conclusion The imbalance of immune response of lymphocyte subsets observed in serofast syphilis may explain the RPR titers change.
RESUMO
To explore the diagnostic values of miRNA141 and miRNA375 for prostate cancer.The expressions of miRNA141 and miRNA375 in serum samples from 30 prostate cancer (PCA) patients,40 benign prostatic hyperplasia patients and 50 normal controls were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).The expression of miRNA141 in tissue samples from prostate cancer was 13.4±7.2 folds of that from benign prostatic hyperplasia while the expression of miRNA375 in tissue samples from prostate cancer was 28.4 ± 10.3 folds of that from benign prostatic hyperplasia.The differential expression of miRNA141 and miRNA375 in sera of prostate cancer suggested that miRNA141 and miRNA375 might be potential tumor markers in clinical practice.
RESUMO
Objectives To investigate the clinical significance of the airway inflammation mediators,eosinophil cationic protein (ECP) and urinary leukotriene E4 (LTE4),in children with respiratory syncytial virus (RSV) bronchiolitis. Methods A total of 120 inpatients with RSV bronchiolitis were classified into atopic and non-atopic groups. And 30 healthy subjects were se-lected as normal controls. Urinary LTE4 was determined by ELISA and ECP concentration in nasopharyngeal secretions (NPS) was tested by UniCAP100 allergen detector. The differences among groups were compared. Results The urinary LTE4 level in atopic group (172.21 ± 67.29 pg/ml) was elevated significantly (P<0.01) than that of non-atopic group (78.21 ± 28.78 pg/ml) and control group (44.22±16.14pg/ml). Significance was also found between non-atopic and control groups (P<0.01). Statistical anal-ysis indicated that urinary LTE4 positively correlated to serum IgE and ECP in children with RSV bronchiolitis (r=0.57,0.49;P<0.01). Conclusions The level of urinary LTE4 and ECP in NPS can provide the reference for treatment and prognosis of children with RSV bronchiolitis.
RESUMO
Objective To compare the value of CEA、CA19-9、CA12-5、CA72-4、CA50 in serum in the diagnosis and therapevtic response of the gastric carcinoma.Methods The 30 gastric carcinoma’s CEA 、CA19-9、CA12-5、CA72-4 、CA50 were detected with electrochemiluminescence immunoassay and radioimmunoassay(15 is the sufferer of transfer of lymph node,15 is not transfer),at the same time choose 30 health person’s serum as comparison. Results The levels of CEA 、CA19-9、CA12-5、CA72-4 increased notably(P
RESUMO
Objective To study the influence of the treatments including temperature and anti-coagulation agent (EDTA-K_2) during the blood samples collection on the ECP level. Methods The serum and plasma samples were collected from 20 childs with asthma and 25 healthy childs under different temperature (25℃ and 37℃). ECP levels were determined by using immobile double-site enzyme amplified chemiluminescence immunoassay.Results The serum ECP level of the treatment under 37℃ was significantly high (P0.05). The serum ECP level was significantly higher(P
